What would cause my Hyundai Santa Fe to start hard every time I put fuel in the tank? It doesn't mater if I just put a couple of gallons in or fill it up.


First sign of pump going bad when it is being filled fuel swirls the dirt around in the tank and when you go to start it it is hard. after the pump is running it runs fine til the next time.

Well it could be numerous if things but you want suggestions...So here's mine..Your gas tank might be vapor locked...This is caused from over filling your gas tank with gas over the years..Its when the pressure in your gas tank becomes greater than your fuel pump. It wont start until the pressure in your gas tank becomes lower then you fuel pump...Sounds crazy...This got me once...I didn't understand it...A lot of people (including me) Go to the gas station and get that extra 50 cent after the gas nozzle clicks off...over time that extra gas will run down the vapor lines intended to burn fumes....Like when you fill a gas can to cut your grass...If you sake the gas can it builds pressure and bows up. But with time that pressure will go away...Well saying that...Your gas tank needs to vent to....So your car burns not only gas but fumes...If you keep over filling your car with the extra gas it cloggs up your vapor canister intended for fumes or vapors...The gas will will go into that canister and clogg up the charcoal that's inside it. (Breaks it down) then the vapors can't get to your carburetor where it supposed to burns it. So what happens is the pressure in the gas tank becomes greater than your fuel pump and then car won't start..Are you with me? Lol Its crazy..Putting a different gas cap can cause the same thing...Simple test...When you open your gas cap to get gas.. Do you heat air sucking in.. Yes you can hear it....A lot of times loosening the cap let's the pressure out and the car will start right up.....Thus might not be your problem but worth telling at the gas pumps to other people..... Just trying to help

I would say a bad Fuel Pump. It's in the gas tank. You can get a whole drop in setup for about $100 +- on ebay. U tube for installation, Be careful.

My 1999 GMC Suburban is hard to start first thing in the morning. It has to turn over for a while before it starts, almost like it has to wait for the fuel to get to the engine. After the first time, it...


Yup!
The fuel pressure valve is stuck open and drains the fuel (via gravity) back to the tank.
Check the fuel pressure regulator / replace.

You might want to put a bottle of "complete fuel system" cleaner ($8 AutoZone) in the gas (not diesel) tank, next fill-up. It may do the trick in a couple of days.

My petrol gauge says I need to fill up but I can't


if you are sure the gas gauge was correct in that you needed a fill up then the problem is a restricted fuel tank vent pipe, this pipe runs next to the fill pipe and lets air out as the tank fills, if it gets obstructed for any reason like a kink then u get the slosh back hard fill issue you are experiencing
